Researchers halfway to cutting carbon fiber costs by 90%

Carbon fiber has been utilized for decades to build racecars, as a means to cut weight while maintaining strength. But until recently, the space-age material has been largely absent from the street on anything but supercars because of the expense to use it. Recently, BMW signaled a major shift in that trend when it starting using carbon fiber reinforced plastic panels on the i3 and i8. This relatively small scale start might be just the beginning; the German company believes that a breakthrough to inexpensively manufacture the lightweight stuff is just on the horizon.
MAI Carbon Cluster Management GmbH counts BMW, Audi, Airbus, the German government and many other organizations as supporters, and it's researching how to make carbon fiber cheaper to produce, according to Automotive News Europe. The company thinks it can reduce costs by 90 percent in the near future. "We've certainly reached a halfway point on our cost-cutting target for suitable carbon-fiber parts," said project head Klaus Drechsler to Automotive News Europe.
Unfortunately, it isn't entirely clear just what MAI Carbon is doing to make such a huge leap possible. However, a recent post on the company's website talks about a new form a carbon fiber using a thermoplastic matrix that could be cured in less than three minutes. That's compared to about 90 minutes in the traditional process with an autoclave.

Why won't automakers slap on a turbo badge anymore?

Where have all the turbos gone? Not the actual pieces that go in the engine, mind you, those are everywhere these days as automakers downsize cylinder counts and boost efficiency and CO2 claims. But the turbo badges and fanfare are missing. Back when turbos were something to get excited about there was "turbo-driven," "turbonium," and "The Turbo Zone," among other silly lines. But now that basically every car is getting some sort of boost even on the lowliest trims, automakers are almost sliding in the turbos under the radar. Or if you look at some of the nomenclature, pretending they don't exist at all. The 911 Turbo badge shows where the car goes from being sane to lunatic. It's an important border. The latest automaker to hide that it has boosted the turbo presence is Porsche with the 2017 911 lineup. Even the standard Carrera models now get turbocharged flat-six engines, meaning the 911 Turbo models aren't quite as special as they once were. Porsche is in a sticky situation with this. The 911 Turbo, after all, signifies where the 911 family takes off from being a sports car and becomes the Ferrari fighter. The 911 Turbo badge shows where the car goes from being sane to lunatic. It's an important border, but now Porsche has crossed it and is trying to downplay the fact. There are a lot of exaggerations with displacement badges today, with claims the 2.0-liter turbo four in a Mercedes C Class equates to a naturally aspirated 3.0-liter six to make a C300. Volvo is pretty far up there, too, saying an XC90 T8 means V8 power, even though it's a 2.0-liter turbocharged and supercharged four with electric assist. I don't know why BMW can't just call the car a 330i Turbo, rather than inflating the numbers up to 340i. Saab tried all of this back in the '90s when it decided to turbocharge its entire lineup, from light pressure units all the way up to models actually called "Saab 9-3 HOT" (for high-output turbo). But then the brand deleted any external reference to the turbo under the hood and people wondered why they were buying a $42,000 four-cylinder convertible. And that didn't turn out well. Even though these turbo replacements often make more power than their naturally aspirated predecessors, they're very different engines. People knew something changed when they exchanged their leased 328i with a 3.0-liter six for a 328i with a 2.0-liter turbo four.

Senior VP Hildegard Wortmann says BMW's electric journey is just beginning

Anyone who questions BMW's effort or sincerity on electrified vehicles should have a chat with Hildegard Wortmann, the German automaker's senior vice president over product management for automobiles and aftersales. I was fortunate to do just that at the Detroit North American International Auto Show earlier this year. ABG: Where might BMW go with electrified vehicles beyond your i3 urban EV and i8 high-performance hybrid sports car? "That [regulatory] train has left the station" - Hildegard Wortmann HW: I think a big advantage is that we now have two bookends: BMW i [green] and BMW M [high performance]. We can use those bookends to foster the BMW brand in total. Are electrified vehicles the answer to CAFE and European regulations? Is that the future? We don't know, but that [regulatory] train has left the station. To achieve all of these regulations worldwide, there is no way to do it without electrification. That is why the activities of BMW i are not just to launch new products. They are our build-up in competence for learning and gaining experience in electrification. We will use those learnings for the total BMW brand. Technology-wise, we now have a really good understanding of what to do, what not to do, how to work with this and how to get a lot of learnings from the infrastructure and everything that goes with it. And depending on how quickly the market takes off, we can scale it and use it across the range. We will use the competence we will have in vehicle electrification for more than just BMW i. There will be other derivatives and electrification of other products. ABG: Do you see BMW offering pure EVs with larger batteries for greater range? HW: That's a big feature of the Tesla. The question is to find the best balance [of range vs. battery size, weight and cost]. On the i3, we tried to have the right balance between how much range customers need for daily driving and how much battery we put in there. The market will show us. We have over a million kilometers driven by consumers in the Mini E and ActiveE and a fairly good understanding that those people are not driving that much. Putting a really big battery with all that weight into a car that is meant for urban mobility does not make sense. ABG: What about extended-range EVs beyond the i3's optional small range extender engine? "This whole EV movement is in its very early stages." HW: This whole EV movement is in its very early stages.
